Chemical Structure
Description
The occurrence of 4-Bromo-2-chloro-1-propoxybenzene is closely related to a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-2-chloro-1-propoxybenzene (CAS 1309933-21-8), molecular formula C9H10BrClO and molecular weight 249.53 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Bromo-2-chloro-1-propoxybenzene (C9H10BrClO) is characterized by a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 4-Bromo-2-chloro-1-propoxybenzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
